Definition

Agent that inhibits the growth of barnacles and other marine organisms on a ship's bottom (an antifouling paint or other coating). Organo-tin compounds have been the most often used agents in this application since they are effective against both soft and hard fouling organisms. However, in spite of their performance, they have a negative impact on the marine environment and their long half life in the environment, has prompted marine paint manufacturers to look for a nonpersistent alternative.
